<!-- The first four sections: "Problem to solve", "Intended users", "User experience goal", and "Proposal", are strongly recommended, while the rest of the sections can be filled out during the problem validation or breakdown phase. However, keep in mind that providing complete and relevant information early helps our product team validate the problem and start working on a solution. --> ### Problem to solve Currently the [Projects API](https://docs.gitlab.com/ee/api/projects.html) has the option to list projects with a specified attribute for `with_programming_language`. [Groups API](https://docs.gitlab.com/ee/api/groups.html) does not have this attribute as an option. As a client of GitLab API, I want to filter by programming language and group id in one call, so I can get as result the list of projects with specified language from the specific group id. ### Intended users * DevOps Engineer * Security Operations Engineer ### User experience goal The user should be able to use the Projects or Groups API to search for projects with specified programming language and group id. ### Proposal Include a way to filter projects by both programming language and group id in a single call, for example by adding `group_id` as an attribute for the Projects API or by adding `with_programming_language` as an attribute for Groups API. For example, for Projects API the url to query would be in the form of: ``` "https://gitlab.com/api/v4/projects?with_programming_language=#{language}&group_id=#{group_id}" ``` Thanks!
